near London in June, not common.” J/. exornatus, Gr. is an Eclytus ; 
and I believe J/. gracilipes, Curt., to belong to AfesoleZus, sensu lato. AV. 
laetus, Gr. = Acrotomus orbitatorius, Holmer. MM. leucostomus, Gr., said to 
have been found rarely about London, was thought by Brischke (Trans. 
Ent. Soc. 1882, p. 155) to be a Tremafopygus, but both the type and 
Stephens’ examples are lost. JZ. narrator, Gr., is Nofopygus analis, 
Holmgr.; and AZ. pectoralis is a Mesolevus. M. quadriannulatus 1 have 
already treated of (Ichn. Brit. i. 167); and JZ. spheginus is a Panargyrops. 
I cannot place Curtis’ inadequately described J/. sfectosus, with its pale 
scutellum, red abdomen with the basal segment alone black and wanting 
areolet. The type of J/. subcompressus is lost and its name better for- 
gotten; AZ. undecimnofatus, Desv., is nothing but a ¢ J. cingulator, 
Grav., of which AZ. submarginatus, Steph., is a typical female; and the 
type of the latter’s J/. ¢horacicus appears lost, since I cannot find it in the 
British Museum. What is Afesolepfus flavopictus, Gr. (I. E. ii. 33, 8), 
the type of which Pfankuch says is lost? Brischke placed it in J/esolezus, 
next to AV. compius, Hlgr., in 1871; Marshall placed it in Pervdissus in his 
1872 Catalogue, and in 1870 synonymised it with JZ. ¢rimacula/us, Steph. 
(Ill. M. vii. 217, Q), the type of which is now lost. But in Mus. Brit. is 
a 9, doubtless that d/. flavopictus recorded by Stephens (dc.) from 
Darenth Wood, agreeing perfectly with Gravenhorst’s description and to 
some extent with that of Thomson’s Cohors z of Jesolerus (O. E. 2043), 
for the face is pale but the areolet is entire with both scutelli pale. 
Bridgman does not simplify the matter at Trans. Ent. Soc. 1887, p. 373.
